This is a game concept that's been bouncing around in my skull for over three years. It's called SERPs & Spyders and the website is here: http://serpsandspyders.com

Currently, there are three game packs available. The title links to the first game pack. The second game pack is here: https://www.thegamecrafter.com/games/serps-and-spyders-pack-... and the third game pack is here: https://www.thegamecrafter.com/games/serps-and-spyders-pack-...

Every collectible card reveals a different SEO (Search Engine Optimization) tactic that can be used in game play, or as a reference/learning tool.

P.S. I should mention I've done professional SEO for about five years now, and "recreational" SEO for about 12 years.
